Clinical Trial Summary

This is a single-blind study consisting of up to 3 cohorts Patients will be randomized 3:1 to Auxora or Placebo. The first 4 patients will be enrolled in Cohort 1. If dose escalation occurs, the next 4 patients will be enrolled in Cohort 2 If dose escalation occurs, the next 8 patients will be enrolled in Cohort 3. The decision to escalate dosing will be made by CalciMedica in consultation with the PI and after the review of safety events in Cohorts 1 and 2.
